As Ron mentioned, we do sell the Aluminum Ron Davis Racing radiators which are ALL aluminum welded construction, NOT epoxied!!!! (similar to the HOWE). We have a few radiators in stock ready for immediate shipment that have the Chevy inlet and outlets. These radiators are excellent for V-8 conversions and will work in L-series powered Z cars as well. We offer two sizes so specify if you have a 240/early 260 car, or a late 260/280 car, (the 280 radiator also fits the 280ZX as well.) They fit the between the frame rails and upper and lower core supports perfectly.

 

These are a “base” radiator, meaning that they do not have mounting flanges and the inlets and outlets are sized for Chev V-8, outlet is 1 ¾”, inlet is 1 ½”.

 

We have ad up in the classifieds as well…

These radiators will also work with the L-series with any carb or aftermarket EFI set up, (the inlet to the radiator at the top is located in such a place that it will not clear the AFM of the stock 280-Z EFI). For use with L-series, it would be best to special order the radiator with the inlet and outlet sized more closely to the Datsun sizes and also to angle the outlet to clear the alternator, (just mention that you want the “L-series conversion” which includes the appropriate sized inlet and outlet and the outlet is angled to clear the alternator). Mounting tabs are also a separate option, but for those wanting to save a few dollars and aren’t afraid of a little fabricating, building your own radiator mounting system is pretty straight forward. The JTR V-8 conversion manual covers radiator mounting pretty well.

 

As a side note, the base radiator will still work with an L-series as is, but requires a reducer at the radiator outlet and VERY creative clearancing of the lower hose of the alternator, (wont clear as OE). In the case our race car, (which I installed a base Ron Davis radiator), I just relocated the alternator to the driver side and used a reducer in the lower hose.

 

With any of these radiators, you will need to source your own radiator hoses. Most auto parts store don’t have a problem with you picking through their inventory of pre-formed radiator hoses. For finding optimum hose lengths and shapes, you can take measurements or mock up using a coat hanger or whatever, then head to your local parts store and find that perfect upper and lower hose, or you can even join two separate hoses with a coupler.
